Inserting gallery plugin in page displaces sidebar position

Hi there,

I’m currently having an issue when trying to insert a gallery into a page, using this otherwise wonderful plugin.

Whenever I try to put a gallery on a page, the gallery displaces the sidebar’s position so that the sidebar shows up much lower then where it should be. Here’s an example: https://www.wanzmusic.com/gallery/colby-college

To try to find out the cause of this, I resized the photo size to 1 pixel by 1 pixel (screenshot of results here), which which showed me that the plugin is trying to take up the page horizontally, despite the fact that the sidebar would not interfere with the plugin based on width.

I tried aligning the gallery plugin to the left with html div codes, but unfortunately that just gave me the same result.

I would very much appreciate any insight into how this problem can be fixed, so that the sidebar will remain in its normal position when the gallery plugin is inserted on a page. Thanks!
